捕食者规避行为：印度太平洋洋中的玻璃鱼群快速游动

ball of translucent pygmy sweepers (Parapriacanthus ransonneti) darts sharply side to side against a reef wall in the Andaman Sea, a defensive reflex that helps confuse predators approaching the shoal. Known commonly as glassfish for their see through bodies, these small reef fish rely on numbers and rapid direction change for survival. The shifting silver mass shows predator avoidance behaviour in real time, striking wildlife footage. 4K, wide angle, vertical medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
